in negative feedback. when an enzyme (negative feed back mechanism) produces too much of a molecule or substance that substance binds to the enzymes allosteric site to hault production of that substance (negative feedback response). and the whole process is the negative feedback loop.

The brainstem regulates breathing by sending signals to the diaphragm to contract and expand. It does this in response to changes in carbon dioxide levels in the blood detected by chemoreceptors. When carbon dioxide levels rise, the brainstem signals the diaphragm to contract more frequently to increase breathing rate and oxygen intake.
The fight or flight response is primarily regulated by the hormone adrenaline (also known as epinephrine), which is released by the adrenal glands in response to stress. This hormone prepares the body to react quickly to perceived threats by increasing heart rate, dilating airways, and redirecting blood flow to essential muscles. Additionally, cortisol, another hormone released during stress, helps sustain the body's response over a longer period. Together, these substances coordinate the physiological changes necessary for survival in dangerous situations.
